EPA's upcoming rulings on confidentiality for data going into the companies' GHG calculations will be important. Those determinations may impact whether companies' reporting is accurate — and whether they can ever be held accountable for their emissions.

Stormwater becomes a big media story during disasters such as floods and hurricane surges, and it's essential to cover the basics then. But there are dozens of related issues that can contribute to the disaster, and covering them in advance can help your audience understand ways of possibly preventing the peak crises.

This user-friendly tool will help you understand and analyze discharges from point sources such as factories, sewage treatment plants, power plants, airports, and feedlots. EPA consolidated data from a number of inventories, making it easier to see who is dumping what, when, and where, and who is known to be in violation of their permit.

The confidential National Air Quality Site Assessment Tool helps the livestock owner/operator figure out how changing on-site practices can reduce emissions of ammonia, methane, volatile organic compounds, hydrogen sulfide, fine particulates, and odors. This may be useful for journalists; whether an owner/operator will discuss the details of their operation or not, there's a story.
